drm/mgag200: deal with bo reserve fail in dirty update path

2013-05-11T20:53:59+00:00

commit 641719599528d806e00de8ae8c8453361266a312 upstream.

On F19 testing, it was noticed we get a lot of errors in dmesg
about being unable to reserve the buffer when plymouth starts,
this is due to the buffer being in the process of migrating,
so it makes sense we can't reserve it.

In order to deal with it, this adds delayed updates for the dirty
updates, when the bo is unreservable, in the normal console case
this shouldn't ever happen, its just when plymouth or X is
pushing the console bo to system memory.

drm/mgag200: Index 24 in extended CRTC registers is 24 in hex, not decimal.

2013-04-12T16:52:09+00:00

commit 1812a3db0874be1d1524086da9e84397b800f546 upstream.

This change properly enables the "requester" in G200ER cards that is
responsible for getting pixels out of memory and clocking them out to
the screen.

drm/mgag200: Bug fix: Modified pll algorithm for EH project

2013-03-28T19:17:49+00:00

commit 260b3f1291a75a580d22ce8bfb1499c617272716 upstream.

While testing the mgag200 kms driver on the HP ProLiant Gen8, a
bug was seen.  Once the bootloader would load the selected kernel,
the screen would go black.  At first it was assumed that the
mgag200 kms driver was hanging.  But after setting up the grub
serial output, it was seen that the driver was being loaded
properly.  After trying serval monitors, one finaly displayed
the message "Frequency Out of Range".  By comparing the kms pll
algorithm with the previous mgag200 xorg driver pll algorithm,
discrepencies were found.  Once the kms pll algorithm was
modified, the expected pll values were produced.  This fix was
tested on several monitors of varying native resolutions.

Drivers: gpu: remove __dev* attributes.

2013-01-03T23:57:15+00:00

CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, and __devexit
from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

drm/ttm: remove no_wait_reserve, v3

2012-12-10T10:21:30+00:00

All items on the lru list are always reservable, so this is a stupid
thing to keep. Not only that, it is used in a way which would
guarantee deadlocks if it were ever to be set to block on reserve.

This is a lot of churn, but mostly because of the removal of the
argument which can be nested arbitrarily deeply in many places.

No change of code in this patch except removal of the no_wait_reserve
argument, the previous patch removed the use of no_wait_reserve.

v2:
 - Warn if -EBUSY is returned on reservation, all objects on the list
   should be reservable. Adjusted patch slightly due to conflicts.
v3:
 - Focus on no_wait_reserve removal only.

drm/mgag200: remove unneeded aper->count assignment after alloc_apertures()

2012-11-20T06:06:26+00:00

alloc_apertures() already does the assignment for us, so assigning the
count member after the alloc_apertures() call is not needed.

Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux

2012-10-04T06:29:23+00:00

Pull drm merge (part 1) from Dave Airlie:
 "So first of all my tree and uapi stuff has a conflict mess, its my
  fault as the nouveau stuff didn't hit -next as were trying to rebase
  regressions out of it before we merged.

  Highlights:
   - SH mobile modesetting driver and associated helpers
   - some DRM core documentation
   - i915 modesetting rework, haswell hdmi, haswell and vlv fixes, write
     combined pte writing, ilk rc6 support,
   - nouveau: major driver rework into a hw core driver, makes features
     like SLI a lot saner to implement,
   - psb: add eDP/DP support for Cedarview
   - radeon: 2 layer page tables, async VM pte updates, better PLL
     selection for > 2 screens, better ACPI interactions

  The rest is general grab bag of fixes.

  So why part 1? well I have the exynos pull req which came in a bit
  late but was waiting for me to do something they shouldn't have and it
  looks fairly safe, and David Howells has some more header cleanups
  he'd like me to pull, that seem like a good idea, but I'd like to get
  this merge out of the way so -next dosen't get blocked."

Tons of conflicts mostly due to silly include line changes, but mostly
mindless.  A few other small semantic conflicts too, noted from Dave's
pre-merged branch.
